Schedule control, supervisor support and work engagement: A winning combination for workers in hourly jobs?

The changing natures of both work and the lives of the U.S. workforce have created an array of challenges for organizations attempting to foster work engagement. To accommodate the work and family needs of an increasingly diverse workforce, many firms are offering flexible work solutions to employees. However, the distribution of these types of organizational resources is unequal, with workers in lower-wage hourly jobs having the least access to any form of flexibility. The purpose of this paper is to examine the relationship of schedule control, as a form of flexible work practice, and work engagement among workers employed in hourly retail jobs. Authors tested a model whereby the relationship between schedule control and work engagement is mediated by schedule satisfaction and perceived supervisor support. A sample of 1343 full-time hourly retail workers was used to address the study's purpose. Hypothesized relationships were fully or partially supported. Implications for research and practice are discussed.     

The Effect of Religious Short‐Term Mission Trips on Youth Civic Engagement

Religious short‐term mission trips are an increasingly popular form of American religious practice, especially among young people. Both organizers and participants often emphasize their transformative nature. However, scholarly efforts to evaluate systematically the social consequences of religious short‐term mission trips are lacking. To address this neglect, our article investigates whether going on a religious short‐term mission trip significantly differentiates youth who engage in civic actions from those who do not. Based on quantitative analysis of Wave I of the National Survey of Youth Religion (NSYR), we find that, controlling for other important factors, taking a mission trip significantly increases the likelihood of adolescents participating in various forms of civic activity, particularly religious‐based volunteer work. Drawing on prior scholarship on religious short‐term mission and similarly focused trips and in‐depth interview data from trip participants, we outline several theoretical mechanisms that likely explain the link between taking a mission trip and civic engagement.     

Investigating joint attention mechanisms through spoken human-robot interaction

Referential gaze during situated language production and comprehension is tightly coupled with the unfolding speech stream ( [Griffin, 2001] , [Meyer et al., 1998] and [Tanenhaus et al., 1995] ). In a shared environment, utterance comprehension may further be facilitated when the listener can exploit the speaker’s focus of (visual) attention to anticipate, ground, and disambiguate spoken references. To investigate the dynamics of such gaze-following and its influence on utterance comprehension in a controlled manner, we use a human–robot interaction setting. Specifically, we hypothesize that referential gaze is interpreted as a cue to the speaker’s referential intentions which facilitates or disrupts reference resolution. Moreover, the use of a dynamic and yet extremely controlled gaze cue enables us to shed light on the simultaneous and incremental integration of the unfolding speech and gaze movement.We report evidence from two eye-tracking experiments in which participants saw videos of a robot looking at and describing objects in a scene. The results reveal a quantified benefit-disruption spectrum of gaze on utterance comprehension and, further, show that gaze is used, even during the initial movement phase, to restrict the spatial domain of potential referents. These findings more broadly suggest that people treat artificial agents similar to human agents and, thus, validate such a setting for further explorations of joint attention mechanisms.     

Controverse relative à la relation entre le stress et la performance au travail : recherche d’explications

Despite many efforts, the relationship between stress and performance remains very controversial. No relational assumption seems to dominate and empirical results present contradictory observations. Pursuing to clarify this relationship, this study has two objectives: countercheck the relation between stress and performance at work and document the potential moderating effects of commitment and job satisfaction on this relation. From information collected by self-administered questionnaires, the statistical analysis demonstrates the absence of relation between stress and performance in the restoration sector and a negative relation for workers in the health sector. As for the moderating properties of commitment and satisfaction, it appears that these variables do not permit to enlighten the relational ambiguities between stress and performance. The discussion presents supporting explanation to the disparity of results between samples.     

教师自主支持与初中生的学习投入:家庭社会阶层与学生自主动机的影响

采用学习氛围量表、主观社会阶层量表、学业调节问卷和修订的课堂投入问卷对1211名初中生进行调查,根据主观社会阶层得分在3分以下、6分以上的标准,筛选出491名典型低阶层(374人)与高阶层(117人)被试,考察教师自主支持与初中生学习投入的关系,以及学生自主动机在其中的中介作用和家庭社会阶层的调节作用.结果表明:(1)教师自主支持与初中生的学习投入之间存在显著正相关;(2)自主动机在教师自主支持与初中生的学习投入之间起部分中介作用;(3)家庭社会阶层在教师自主支持影响初中生自主动机进而影响其学习投入的过程中起到有中介的调节作用.     

家长投入对中小学生学业投入的影响:有中介的调节模型

以北京市12所中小学的4160名学生为调查对象,采用层次回归方法考察了家长投入对子女学业投入的影响以及家长自主支持/控制的教养风格和子女的学业心理需要满足在其中的作用。结果发现:(1)中小学生的家长投入程度随学段升高而降低;(2)家长注重在家辅导方面的投入,在参与社区及学校活动等方面的投入较为欠缺;(3)家长投入对子女的学业投入具有显著的正向预测作用;(4)家长自主支持/控制的教养风格在家长投入与子女学业投入的关系中起调节作用,且该调节效应部分地通过子女的学业心理需要满足这一中介变量产生作用。     

The “dual usage problem” in the explanations of “joint attention” and children’s socioemotional development: A reconceptualization

The term “joint attention”, which first gained currency in the early 1960s in studies of the development of language and symbolic thought, remains significant in the developmental literature. However, its meaning is unclear. A definitional problem exists similar to what Patterson [Patterson, M. L. (1982). A sequential functional model of nonverbal exchange. Psychological Review, 89, 231–249] described as the “dual usage” problem in the study of behaviour. The dual usage problem manifests when the behaviours of interest are used interchangeably with the function served by those behaviours. Similarly, the behaviours or skills that are taken to show joint attention are used interchangeably with the functions served by these behaviours. Scant attention is given to how the behaviours are generated and regulated and how they contribute to development. The purpose of the present position paper was: (1) to identify and illustrate the ways in which the behaviours and functions of joint attention have been confounded in the literature; (2) to provide a revised operationalization of joint attention incorporating the idea of Consummative Joint Attention, which is defined as a process variable that integrates these two theoretically different and complementary aspects of “joint attention;” and (3) to test this revised definition with evidence from a sample of hearing mothers and their 18- to 36-month-old hearing or deaf toddlers. We suggest that a reconceptualization and revised definition of joint attention as a process served by a particular sequence of complementary and well-timed events in the behaviour of mother–child interaction are particularly well-suited to testing joint attention as an early prelingual mechanism and to detecting early problems with psychosocial and adaptive development created by ineffective patterns of social interaction.     

Combining additive representations on subsets into an overall representation

Many traditional conjoint representations of binary preferences are additively decomposable, or additive for short. An important generalization arises under rank-dependence, when additivity is restricted to cones with a fixed ranking of components from best to worst (comonotonicity), leading to configural weighting, rank-dependent utility, and rank- and sign-dependent utility (prospect theory). This paper provides a general result showing how additive representations on an arbitrary collection of comonotonic cones can be combined into one overall representation that applies to the union of all cones considered. The result is applied to a new paradigm for decision under uncertainty developed by Duncan Luce and others, which allows for violations of basic rationality properties such as the coalescing of events and other framing conditions. Through our result, a complete preference foundation of a number of new models by Luce and others can be obtained. We also show how additive representations on different full product sets can be combined into a representation on the union of these different product sets.     

Representation, interaction, and intersubjectivity

What the participants share, their common "sense" of the world, creates a foundation, a framing, an orientation that enables human actors to see and act in coordination with one another. For recurrent activities, the methods the participants use to understand each other as they act change, making the intersubjective space in which actors operate richer and easier to produce. This article works through some of the issues that emerge from a close examination of intersubjectivity as it is managed through representation and interaction. The data that are presented document, in detail, a sequence of related interactions, within and across episodes of cooperation, where continuity and change can be observed. The emergence of conversational structure and coordinating representations are significant milestones in the long-term development of a representational practice that support the runtime co-construction of intersubjective space. Conversational structures emerge interactively to mediate recurrent points of coordination in the domain activity, and only secondarily the conversation itself. Coordinating representations change the representational practice of the participants by making it easier to manage their "shared view" of the collective work, enabling the participants to make progress, expand the field of the common activity, while exhibiting more control of if and when explicit grounding occurs.
